0000017266 00000 n Your message explains this. Well occasionally send you account related emails. My consumption only power-factor when I look at it from the installer toolkit says around 1.0, but the apparent power is nearly double the watt measurement which implies a pf of around 0.5. From above I derive the conclusion that the reason of the presence of all 3 phases on the 'power input' connector must be to measure the voltage of each phase (as there appears no other plausible reason for wiring all 3 phases on this connector). WebC. I am quite sure my problem is based in the start-up voltage and minimum voltage. Though this time I had someone add my PR to the list of PRs that should be included in 2020.12.1. I'm still looking over the code and the different paths taken and the different types of envoy devices with and without features. Note: my CTs are currently disabled. meter_issue One or more meters on the system are reporting unusual 0000093917 00000 n Web The Envoy-S Metered uses precision Current Transformers (CTs) to measure PV production (accuracy 2.5%) from the solar main supply switch and home energy consumption from the AC mains.

Application plans have minute and month limits. In addition, the Envoy-S Metered provides revenue-grade production data and allows for the monitoring of a sites energy load, thus offering significant advantages over other PV system monitoring equipment. Users can access energy production and consumption data through Enphase Enlighten cloud based monitoring software. 0000033107 00000 n Envoy Status (I have observed bogus values for 'production' and 'consumption' in range between 0 and 2). I'm wondering if someone with a functioning pre-IQ envoy could browse the production json value and post your results. I tested your modified envoy_reader with my Envoy-S Metered Multiphase with metering disabled (no CT's). It is important to understand these differences when installing Envoy CTs. WebTo enable correct operation of the Enphase Home Energy system components (including the Enphase AC Batteries), the Envoy must correctly measure the current flow across WebMeasure for voltage across individual wires and connections in the charging system. It only reads envoy/production.json. There was a reply in the Home Assistant Community forum where a person took this screenshot. 0000026874 00000 n period_start and period_end tell you when the minute (in this case) started and when it will end. @rct If you have code changes could you post it to GitHub for a possible merge? 0000012231 00000 n 0000375146 00000 n If the total duration requested is more than one day, returns one day of intervals. An Enphase team member may follow up with you about your feedback. This is what is shown on the envoy/home page when CT's are not enabled: Let me know if you need more information or help. I currently check the /api/v1/production data in a browser and refresh manually. The API accepts a number of parameters. Exactly: I have only CT's installed for measuring Consumption "CT's" is plural but consumption/eim/activeCount only shows 1. I see now that there was mention of these URLs in the Envoy-S data scraping blog that I missed previously. 0000452685 00000 n If the system has both production and consumption CTs installed, you can see which meter is affected by checking the meter status on the Devices screen. The consumption measurements received by Enlighten do not appear to include storage activity. I agree a better solution would be to have additional parameters. So I just display the values unless the device actually does not support metering. I need to understand how the Home Assistant configuration interface interacts with envoy_reader to configure it. 0000048897 00000 n WebAN_6612_032 Energy Measurement in Split Phase Systems Using 78M6612 Rev. The text was updated successfully, but these errors were encountered: @lnlp Would it be possible for you to post a copy of your /production.json? Each envoys element includes the following: Returns a list of systems for which the user can make API requests. Do not nofollow your links to Enphase. 0000002893 00000 n To enable correct operation of the Enphase Home Energy system components (including the Enphase AC Batteries), the Envoy must correctly measure the current flow across the electrical circuits via the CTs. If your system has stopped reporting data, youll see a problem message like this: Learn what you can do if your system stops reporting data. My utility company (Xcel) has a great program where the rate is ~$0.04 per kWh which is awesome. All times are GMT-5. Perhaps for compatibility there should be three available entities for the wNow values in Home Assistant: Having these three elements would allow the user to override Envoy reader's choice if necessary as well as track both on systems with CTs if the user chooses that. There are 1609 meters in a statute mile. The new version of API (v4) is available at: developer-v4.enphase.com. WIRING EXAMPLE:Envoy S Wiring recommendation Subboard Typical 1Phase Net Metering, WIRING EXAMPLE:Envoy S Wiring NSW METERING recommendation 1Phase TWO METERS for Net Metering. Today is medium overcast so that is adding to low production. Specifically it has to do with the power factor. In my comments above, I was arguing for the case to still be able to get the inverter numbers even if metering is enabled. 0000003055 00000 n It seems the the values are almost the same and they are both updated every 5mins. Envoy S Production data is not read when not using current transformers which renders reported Production data useless. 0000014056 00000 n Planning and installing consumption monitoring Install a phase coupler on the load side of the over-current protection device. I upgraded to HA 2020.12.1 today and the /api/v1/production counters now appear to report properly in HA. There isn't any identifying object info inside the two objects in the top-level list.

Contact us for sales, quantity discounts and expert reviews for the Enphase CT current transformer for Envoy. Meters are abbreviated using a lower case "m" in measurements. (I suspect something like: electrical induction metering). Other than reducing http calls to the envoy device, is there another benefit to pull the production data from the two pages rather than one? That may be a clue. All requests support an optional callback parameter. Here's my output. It'll be removed from the code. I does give a way of polling the detailed data from each CT for what looks to be all three phases, whether it is installed or not. 0000063893 00000 n My Envoy reports tiny metered values while metering is disabled. When True the Envoy should be handled as endpoint_type "PC", when False as endpoint_type "P". Active does not imply that the device is currently reporting, producing, or measuring energy. I added some more detail in the Issue #41. I'll have to look into this one a bit. If you don't see any voltage pulses, replace the sensor. So it looks like you need to join with /ivp/meters based on eid to know what you are looking at and whether it is enabled. In Home Assistant ('Enphase Envoy' add-in which uses envoy_reader) I do not get actual values for all 4 values shown in /api/v1/production. I have not done the math to calculate the cost savings for such a small battery (10 kWh) on the Ford. CT Measurements" from a consumption CT on one of the phases. Instead of /stream/meter has anyone tried /ivp/meters/readings? There are no gaps in the time series. 0000232378 00000 n 0000139909 00000 n My Envoy also reports a realistic value for data/xxx-consumption/ph-a/v. As previously requested please add the following output parameters: I removed the inverter data and right now the values are zero due to no sunlight, but you should get an idea of what would be sent to Home Assistant once that sensor code is updated. Thanks for your continuing efforts! to your account. Sign in If a meter or meters are installed on the system, measurements come from the meter; otherwise, measurements come from the microinverters. If you see a green checkmark, then your system is fine with normal system production. Though I wonder if something like this would solve the problem, Add a function called hasMeteringEnabled() which will return True if production[1]eim activeCount is >= 1 else False, envoy_reader/envoy_reader/envoy_reader.py. When I investigate the raw numbers from interrogating the envoy direcly it actually shows me the low power factor. When this condition is detected, the response code is 500 and the response body is: Returns a time series of energy consumption as measured by the consumption meter installed on the specified system. metered_consumption wNow: 0.836 (gets truncated to 0). WebThe use of any other type of CT will result in incorrect power measurements, and may permanently damage the WattNode meter. The darkish overcast looked like possible little snow storm coming. Prefix multipliers based on powers of 10 are used to convert meters to other SI units. In general, a Meter Issue indicates a system where on-site maintenance may be required. The production or consumption measurements received by the Enphase Cloud are negative. If the system has both production and consumption CTs installed, you can see which meter is affected by checking the meter status on the Devices screen. If the response includes trailing zeroes, such as [909, 4970, 0, 0, 0], then no data has been reported for the last days in the series. Gaps in reporting are not filled with 0-value intervals. Have an assistant crank the engine for a few seconds while you watch the meter's readout. Here is low light at the end of the day. <>/Metadata 3482 0 R/ViewerPreferences 3483 0 R>> WebThere is an issue with my envoy meter measurements Expand Post Translate with GoogleShow OriginalShow OriginalChoose a language DownloadDownload Show more WebIf the system has both production and consumption CTs installed, you can see which meter is affected by checking the meter status on the Devices screen. 2 0 obj A phase coupler for communication with the inverters is not built-in to the Envoy. Unlike ratio CTs with current outputs, these CTs are internally burdened to produce a safe 0.333 Vac output voltage, therefore, shorting blocks are not needed. Right after connecting the power lines to the grid I already have some statistics of the grid meter (in the Netherlands called the Slimme meter, which you can read through the P1-port using i.e. However, each request may optionally include it. In 'case B' one may wonder why the 'power connector' on the left exists and allows to wire all 3 phases. All rights reserved. 0000007176 00000 n Better ($) electric cars are using heat pumps more effectively to heat. Got your message a little before 11am my time so low production is just winding down. The production or consumption measurements received by Enlighten are negative. If the consumption measurements received by Enlighten do not appear to include storage activity, there are two possible wiring issues that can cause this: The Meter Issue status will continue to display until Enlighten receives 24 hours of meter measurements that indicate the problem has been addressed. Examples in this documentation exclude the API key and the user_id for clarity. Installing the Enphase Envoy-S Metered If there is a problem, MyEnlighten and the Enlighten mobile app show a message to help you know what to do next. These come from mainly 3 pages (excluding Envoy running <3.9 firmware), I would propose removing the original consumption parameters and adding additional parameters (lets prepend them in this example with metered_*. Envoy S Production data is not read / read incorrectly when Copyright 2014 SolarReviews All rights reserved. /api/v1/production does not contain "readingTime" but /production.json "type": "inverters" does. It wouldn't make a difference inititially when just measuring solar since solar generation is balanced. 0000452724 00000 n EIM - Your guess on the meaning of the acronym is 'electrical induction metering' is possibly correct. 0000032874 00000 n There is an issue with your envoy meter measuremen Remote problem-solving The Envoy lets you pinpoint performance issues instantly and resolve them remotely, before they get in the way of system performance. Each system element includes the following: Return values for status include the following, and are listed in priority order: Returns a listing of active devices on the given system. That's why I'm asking to track the above as separate issues. @OllemGit One case that is not handled, if you want the inverters current production and WH lifetime production, with metering turned on, you can only get that from production.json. Observation: metered values get truncated instead of rounded. My Envoy reports a realistic value for data/production/ph-a/v while no CT's are installed. Anyway, I tried reversing both the production CTs and swapping their phases.
